Title: Method for welding low alloy steel
Inventor: YOSHIOKA TAKATOSHI
IPC: C21D6/00
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To obtain a welded structural material having high reliability without developing an SR crack by holding to a specific temp. for long time at the time of executing a stress relief annealing treatment and thereafter, raising the temp. to execute the stress relief annealing treatment. SOLUTION: A cause of the development of the SR crack after welding is because the slippage in grain boundary of the crystal is precedingly developed to the slippage in the crystal grain at the part affected by welding heat effected part, in the process of releasing of the residual stress with the welding work. Therefore, the intermediate heat treatment is desirable to be such treatment at low temp. that the stress releasing phenomena is not developed. That is, in the case of applying the stress relief annealing at about 700 deg.C after welding in the welding work of a 21/4Cr-1Mo steel, in this teme. raising process of 400-450 deg.C, this welded steel is once held for long time, and the low temp. treatment is executed. Thereafter, again this steel is raised to about 700 deg.C to execute the stress relief annealing treatment.  By this method, the welding method, in which the preheating temp. for preventing the SR crack is not executed in high temp., can be provided.

Title: Heat-sensitive recording paper
Inventor: HATA TOSHIAKI
IPC: D21H17/67
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To reduce the curl of wound retention of recorded paper after recording by using base paper whose rate of machine loading of a filler is in a specific range in terms of wt.% and winding a heat-sensitive recording layer so as to direct its layer face inward. SOLUTION: Heat-sensitive recording paper wound in a small winding state so as to direct its layer face inward has the curl of wound retention so that the heat- sensitive recording layer face is turned inside. However, when recording is performed by various printers, the recording layer face is effectively drwan in reverse in a direction in which the curl of wound retention is rectified by a platen roller, and the wound retention before recording is moderated to some extent. Further, by using base paper, in which the rate of machine loading of a filler such as clay and talc is made to be 20-30wt.% relative to the total amount of solid content of the base paper, as a support member of the heat-sensitive recording paper, a drawing effect by the platen roller, etc., is easily produced, and the curl of wound retention after recording becomes small.  When the rate of machine loading of the filler in the base paper is smaller than 20wt.%, an effect of making the curl of wound retention small after recording is not much produced. Furthermore, when it exceeds 30wt.%, the strength of the base paper is extremely reduced.

Title: Uninterruptible line changeover circuit
Inventor: CHIBA TAKASHI
IPC: H04L1/22
Filed: 1991-01-18
Abstract: PURPOSE:To eliminate a line interruption time at changeover between an active line and a standby line by allowing a receiver to detect a phase difference with an identification signal received by a transmitter, matching the phases of the signal from the active line and the standby line and changing over them. CONSTITUTION:An identification signal is inserted to a transmission signal at a transmitter 1 and a branch circuit 12 sends an identical signal to an active line and a standby line. A time difference detection means 21 of a receiver 2 extracts an identification signal from the transmission signal sent via the active line and the standby line. The means 21 detects a time difference between identification signals from the extracted signal and a control means 24 delays a reception signal from the active line and the reception signal from the standby line based on the time difference by using 1st and 2nd delay means 22,23. As a result, the phases of the two reception signals are matched. Since a changeover means 25 implements changeover after the two signal phases are matched by a command from the control means 24, the interrupt time at changeover is eliminated.

IPC: C21C7/10
Filed: 1981-01-16
Abstract: PURPOSE:To remove the materials stuck on the outside circumference of a molten metal immersion pipe quickly, safely and surely by providing a cylindrical body having teeth for removing said materials on a traveling dolly freely turnably, and driving the same to move upward around the immersion pipe. CONSTITUTION:A traveling dolly 13 is positioned below a vacuum degassing tank 19 or the like. While pressure oil is supplied to oil pressure cylinders 161, 162, a handle 18 for operating an air pallet is operated to glide an air release table 8, thereby positioning a tooth crown 2 to right under an immersion pipe 9. Then, the crown 2 ascends in the form of penetrating through the pipe 9, and abuts on the base metal and slag stuck to the outer side of the pipe 9, thereby stripping these. The crown 2 is lowered by operating the cylinders 161, 162, and the crown 2 is rotated slightly by energizing the air pallet, after which it is moved upward again to remove the slag. Thence, a table 14 is moved upward to place the leading ends of teeth 1 on the flange 21 of the pipe 9 and the flange 21 of the pipe 9 is removed from the flange 20 of the tank 19. At this time, coil springs 7 act as cushion materials supporting the pipe 9.

Title: Exhaust heat recovery boiler
Inventor: HASHIMOTO MASAYUKI
IPC: F22D11/00
Filed: 1989-01-13
Abstract: PURPOSE:To prevent the wall thickness of a low pressure evaporator heat transfer pipe from being reduced by erosion and/or corrosion by constituting the low pressure evaporator heat transfer pipe with a low alloy steel which contains Cr. CONSTITUTION:Ammonia is added to the water supply, and sodium phosphate is poured into a high pressure drum to raise pH value therein, and the heat transfer pipes of a low pressure evaporator 5 are formed by a low alloy steel which contains Cr more than 1%. With this constitution the pH value of the water in the drum falls because the supply water passes through a low pressure fuel economizer 6 and goes into a low pressure drum 8 and because of a high gas-liquid distribution rate of ammonia in the water supply. Furthermore, the water supply is led to a low pressure evaporator 5 by a low pressure circulation pump 9, and it becomes a two phase flow in steam and water. Even if the flow becomes a turbulent flow of a low pH value, the erosion and corrosion of the heat transfer pipes are much reduced because the heat transfer pipes of the low pressure evaporator 5 are formed with a low alloy steel with Cr more than 1% which excels in erosion resistance and corrosion resistance.
